Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Power Steering Fluid Check

Locate the power steering fluid reservoir.
If low, top off with the recommended fluid (Toyota PS Fluid).
If fluid is contaminated, consider a fluid flush.

3. Serpentine Belt Inspection

Remove any necessary covers to access the serpentine belt.
Inspect the belt for cracks or wear. If damaged, replace with an OEM belt.
Use a belt tensioner tool to release tension and remove the old belt.

4. Wheel Bearing Inspection

Lift the car using a jack and secure with jack stands.
Spin each wheel; listen for grinding or whining noises indicating bad bearings.
If noise is present, remove the wheel and hub assembly. Replace bearings if necessary.

5. Transmission Fluid Check

Locate the transmission dipstick or fluid check plug.
Pull the dipstick and check fluid level; add fluid if low.
If fluid is dark or has a burnt smell, consider a complete fluid change.

6. Differential Inspection

If applicable, remove the differential cover to inspect fluid levels.
Check for metal shavings or debris in the fluid indicating wear.
Replace fluid with manufacturer-recommended gear oil.
